The 35th Annual Lower Michigan Mathematics
Competition will be held at Kalamazoo College this year on Saturday, April
2. Students from colleges and universities in Michigan will gather
to challenge themselves on 10 interesting problems, working together in
teams of up to three people. The competition takes place in the morning
and after lunch there is a discussion of the solutions. You must signup by Wednesday, March 16 either on Prof. Cinzori's door (VWF 216) or send him an email at cinzori@hope.edu. You may register as a team (of two or three) or individually (and you will be placed on a team). It has been a few years since Hope has held possession of the Klein Bottle Trophy and it is time to bring it back to campus! 
Math Online: What pi sounds like 

Since today is Pi Day, we thought you
might be interested in what pi sounds like. There are a number of videos on
You Tube where people have tried to put the number pi to music. We
thought that the video by Michael John Blake found here
was one of the best. Other things to do today: 
Problem Solvers
of the Fortnight 

Last week’s PotF:
A new elementary school
teacher wants to stock her inclass library, but, since she is a recent
graduate and therefore somewhat destitute, she has very little capital.
Imagine her delight when she comes across a plethora of children’s books
at a church rummage sale! They have boxes and boxes of paperbacks with
a price tag of 4 for $1. Then there are many short hard cover books
on a shelf tagged $1 each. Finally, she sighs wistfully at the shelf
containing beautiful, early edition hard covers for $15 each. She withdraws
$100 from the cash machine and gets busy with her selections. Determine
all of the ways she can buy exactly 100 books with exactly $100. 
Problem of the
Fortnight 

A certain dodecahedron
has edges of length 10 cm. If a fly lands on a vertex of this dodecahedron
and then walks along only the edges, what is the greatest distance the
fly could walk before coming to a vertex a second time and without retracing
an edge? Justify that your solution is optimal. Write a complete solution (not just the answer) on a dodecahedron and drop it off in the Official Problem of the Fortnight Slot outside VWF 212 by 3:00 pm on Wednesday, March 30. As always, be sure to include your name, the name(s) of your professor(s), and your math class(es)  e.g. Moe Mentum, Dr. Senor Moment, Math 112  on your solution.
